` To all 'whom t may concern.'

Be it knownthat I, ANGELO OSLER, a citi-` v zen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Window-Guards, of which the following is declared to be a full, clear, and exact description. i'

This invention relates to window guards,

and one o1 its objects is to provide a window guard of improved construction capable off' being readily installed in place in front of a window, and which is adjustable in Width so as to accommodate windows of`various sizes.

-Another `object 'is'to provide a guard which may be quickly and easily attached to or detached from its supports.

Another object is to provide a window guard which does not interfere with, nor hinder the `tree movement of the windo-w sash, hut' is positively1 locked Vin place by the sash whenever the latter is in a raised position. i A

Another object is tov-provide a window guard with locking means for lockingthe lower sash when fully lowered, and for locking the guard in place when the sash is raised or partly raised. Y Another object is to provide a window guard capable of being collapsedso as -to take up little room when -not in use.

W'ith these and other objects and advan-H tages in view, this invention consists in the several novelfeatures of construction, arrangement and combinationl of parts hereinafter fully described and particularly accompanying drawings, in which A 'Figure 1 is a front elevationoi' a portion of a window, showing a simple form of winv dow guard embodying the present invention,

secured in place infront of the lower sash l of said window; Fig. i2 is a horizontal section ltaken on the line 2,-.-2 ofFig. 1; Fig.

S is a vertical section taken `on the line 3 3 Y of Fig. 1; Figli is a perspective view of the locking mechanism and 'a fragment of the r window; Fig.- 5 isa detail vertical section taken on the line of Fig. 2; Figf is' a detail horizontal section taken on the line i--Goi Fig. 5; Fig."7 is a detail horizontal :motion through the guard proper, taken on of the locking mechanism; Fig. 12 is a hori` zontal vsection taken on the line 12-12 of Fig. 11; Fig.,V 1.3 isja side elevation of a second modified form of locking mechanism; and Figultis a plan thereof.

Referring Vto said drawings, andfir'st lto Figs. 1 to 10, inclusive, which Villustrate the ypreferred embodiment of the inventiomthe reference letter, designates the sill, B, B, the jambs of awindow frame, and C, D, the upper land lower sash, slidably mounted therein. Secured to the window stops, o, are two upright supporting members, 14, for the window guard, here shown as formed of channel iron bars,extending from'a point Y near the sill to one somewhat above the up-V perv or meeting rail ofthe lower sash when `fully lowered. Said supporting members,

14, may be secured to the window frame by screws, or otherwise,-asldesired. Theguard proper 1s seen at E, and is removably secured to said upright supporting members, `111. In its 'preferred form, said guard proper comprises upright end lmernbers,`15, preferably formed. of angle-iron bars for the `purpose of obtaining strength, intermediate upright members,v 16, and"horizontal lmembers, 17, extending :between thel upright end members, 15, andconnected with `said upright endV members' and intermediate members to form `a strong,fsubstantial and rigid open work frame or grille work lor grating. vThe horizontal members, 17 of said guard proper are suitablyy spaced apart,

to prevent the passage of a personv between them, and the upright', intermediate members, 16, are so spaced as to insure strength and rigidity of structure. Y To providev for adjustment for windows of Vdifferent widths,

the guard proper is made of two4 sections,

slidably connected witheaeh other, and asv shown, each horizontal member comprises av tube and a rodvsliding therein, but the horizontal members may comprise angle-iron bars, channel bars, or the like, the one being ,glidabjly `connected."withy the other, and the.

member.

the upright member, its end being` headedV down upon theouter face of the upright The outer ends or' the horizontal members, 17, are rigidly secured in the end lugs, 18, as, for instance, by means of pins, 20, andthe other ends of the` tubular members, 17h, are rigidly fastenedV in the lugs, 18a, but the tubes slide through the lugs,

18a, which are intermediate the ends of the tubes, and said intermediate lugs also form supports on the upright member, 1G, for the tubes and rods contained therein. Preferably, the tubes on each end upright have rods interposed between them, as seen in Fig. 1, so that thelugs on each intermediate upright are rigidly fastened to the alternate tubes, the intermediate tubes sliding through the other lugs. rl`he lugs, 18", have set screws, 21, threaded therein and adapted to bear against the rod members, 17, for connecting the two sections of the guard proper and fixedly holding them in any poikV sition of adjustment with respect to each other. By reason of the swiveled connection between the upright and horizontal members of the guard proper, it can be collapsed, as shown in Fig. 9, for the purpose of shipment or storage. Preferably, one or more of the lugs are provided with fingers, 18C, projecting across an edge of the adjacent Vupright member, as shown in Figs. l, 7 and 8, for thepurpose of arresting relative movement between the upright and horizontal members when they are brought to a position at right angles to each other. This is simply a matter of convenience and facilitates the placing of the guard proper in position with respect to the locking mechanism.

The means for locking the guard proper to the window frame will now be described. Riveted, or otherwise ixedly secured to the lower ends of the upright .supporting members, 14, are two brackets, 22 (see Fig. 10), each having a horizontal ear, 23, vformed with a vertical aperture, for the reception of a stud pin, 24, which projects down from the horizontal ear, 25, of a bracket, 26, there being one bracket rigidly secured to the lower end of each uprightend member, 15. When the guard proper is unlocked or unlatched from the upper locking devices, it may be detached from the brackets, 22, by

lifting' it up until the pins, 24, are withupper end of the guard proper with the l window frame will now be described. Riveted or otherwise fixedly secured to the upper ends of the upright end members, 15, are two keepers, 27 (see Fig. 4), which are adapted for engagement with lock bolts or plungers, 28, that are movably mounted on the upright supporting members, 14. In the preferred form of the invention, said lock bolts or plungers, 28, are slidably, but nonrctatively mounted in horizontal ears, 29, 29a, ofk brackets, 30, which are riveted or otherwise rigidly secured to the upper ends of the supporting bars, 14, and each lock bolt or plunger is here shown in the form of a square -rod or bar sliding through square holes formed in said ears, 29, 29a. A washer, 31, secured to the upper end of the lock bolt by the screw, 32, rests on the upperear, 29, and supports the lock bolt or plunger. The keeper, 27, is provided with an opening, 33, which is adapted to receive the lock bolt or plunger when brought into register therewith, thereby locking the guard proper to the upright supporting members. Preferably, the lower' end of the bolt, 28, is beveled ofi" and the upper face of the keeper, 27, has a correspondingly beveled place for facilitating the lifting of the lock bolt when the guard proper is moved into locked position. with said lock bolt, 28, is a slidable locking member, 34, which is capable of extending over the upper or meeting rail of the lower sash, thereby locking said sash down, and also capable of locking the lock bolt, 28, against movement relative to the latch member, 27 In the preferred form of construction, said locking member, 34, is in the-form of a horizontally sliding bar, slidably mounted in the lock bolt, 28, near its lower end, whereby .it may be pushed over the top of the upper or meeting rail of the lower sash or withdrawn therefrom, so as to lie adjacent the stile of the window sash. Means are provided between the bracket, 30, and lock bolt, 28, for preventing endwise movement of said bolt, and in the preferred form, the locking member, 34, is provided with an upwardly extending pin, 35, adapted to enter a hole, 36, in the lower ear, 29a, of the bracket, 30, whenever the locking member, 34, is pushed over the top of the upper rail of the lower sash far enough to bring the pin, 35, and hole, 36, into register with each other. W'hcn, however, the locking member, 34, is retracted, and the pin is brought out of register with the opening. 36, its upper end engages with the lower face of said ear, 29a, and prevents upward movement of the locking member, 34, and

Connected lli;-

lock bolt,28; consequently, the lock bolt cannot be withdrawn from engagement with the keeper, 27, and therefore the guard proper cannot lbe removed until the locking .member, 34, is shifted back over the sash to bring the pin into register with the hole in the ear, 29a. Preferably, each locking member, 34, is provided with a shoulder. 37

see Fig. 6) arranged to strike against the face of the lock bolt, 28, Vwhen the pin and hole are in register, and for convenience, 'a knob, 38, is provided on the extreme end of each locking member, 34, which may be grasped in manipulating it.VA Conveniently, f the lower end of the bracket, 30, is formed with a horizontally extending guide member,

39, which has an outwardly curved, vertif cal edge for guiding the keeper, 27, when the guard proper is being put in place, and said bracket is also formed with a lug, 40, be-

yond said guide, 39, against whichy the keeper, 27, strikes whenever the lock bolt,

- 28, and opening, 33, of the keeper 27 are in register'.

bers, 34, are pushed back over the' top of said sash, thereby bringing the pins, 35, and holes, 36, into register. The guard proper,

E, is then taken hold of and raised until the stud pins, 24, are withdrawn from the apertures inthe ears, 23, after which'V the lower l end of the guard proper is swung out slightly and then lowered to disengage the keepers, 27, from the lock bolts, 28. The guard may then be folded into the collapsed condition asshown in Fig. 9, and stored in some convenient place.V The `locking members, 34, now act as sash locks for the lower sash. To replace the guard proper, itis extended into Aopen position, the stud pins, 24, inserted into the apertures of the ears, 23, and the upper end of the guard proper pushed back until the` keepers,27, engage the lock bolts, 28, and raise them, after which they drop into the apertures, 33, in said keepers. By drawing forward the locking members, 34, the' guard proper is locked in place, and cannot be removed until thei locking .members, 34, are again pushed over the top of the lower sash.` Whenever the lowersash is raised,

or partly raised, its 'stiles lie in front of thev c heels of the locking members, 34, thereby f AVpreventing them from being pushed back,

and whenever held in this forward position,

the lock bolts, 28, are'prevented from being raised because of the pins, 35, which strike against the lower faces of lthe ears 29a.

, In' the `modified form of locking mechanism shown in Figs. 11 and V12, `the lock bolt, `'28,is rotatively mounted in the ears of the bracket, 30a, and the locking member,

- 34a, is fixedly secured to saidlock bolt near l its lower endf As in the preferred con` struction, said locking member isprovidedv To removeIthe guard proper,` E, from its supports, the lower sash is first fully lowered, after which the locking memf with an upstanding pin, 35a, which, when brought into register withv'the aperture, 36a, permits the locking member, 34a, and lock -b olt,28a, tobe raised.V By swinging the locking member into the position shown in dottedl lines in Fig. 12, the pin, 35a, is

brought under the body of the ear, thus preventing the lock bolt from being raised.

In the modified form shown in Figs. 13 and V14, the vlock bolt, 28", has a transversely `extending pin, 35h, secured to it, which engages with the under side of an ear or flange,

*30",y which projects out from the supporting member, 14h, but which pinmay be brought into register with a., slot, 36", in said ear or flange, and the lock bolt may then be raised. A locking member', 34h, here shown in the form of apin extending through the lock bolt,"'28b, and ixedly secured therein, may

be swung into the position shown in dotted lines in Fig. 14, thereby locking down the lower sash and bringing the pin, 35h, into register with the slot, 36h, for unlocking the Vguard from its'supp'orts, andsaid locking member, 34", may be 'brought intothel position lshown in solid lines, thereby bringing thepin, '35", outv of register with: theslot, 36h, and preventing raising ofthe bolt-,consequently lockingthe guard to its'supports, asin the other forms.

It is'perfectly evident from the above description that" although the guard proper is positively locked in place, the lower Vsash,

f may be freely raised and lowered, and that ywhilein any raised 'posit1on,etheguard is C positively locked in'place, but when thesash islowered to Vvvits lowermost position, the guard may be removed,- but'only at such time, fand vthen Vonly by moving the .locking I members acrossfthe upper rail of thev lower "f sash, thereby locking it down, so that 'it is impossible to remove the guard proper from glass, or

iio

The window guard may be readily' in-y stalled,and nofspecial tools are required for fastening 1t in pla'ce, and the wood trim is H-not necessarily marred,rexcept for the screwholes which-receive the screws that fasten the supporting members in place. j' i K The guard proper may be readily adjusted in width to accommodate various sizes of windows, the intermediate uprights, 16, being brought closer to each other as the guard is made wider, and farther apart as it is made narrower, but always preserving a Vsymmetrical appearance for the guard.

More or less variation ofthe exact details iso locksaid guard against removal.

from the spirit of this` invention, and I desire, therefore, not to limit myself to the exact form of construction shown and described, but'intend in the following claims `to point out all ofthe invention disclosed.
